2.0 Features

Refer to Figure 1 for the following information.

The MNE-240 Series E-Panel incorporates all the AC and DC wiring bus-bars and disconnects required to connect the Magnum MS-AE Series inverter/charger system.

It also provides additional room to install additional equipment, such as the MidNite Classic Charge controller (with accompanying solar array breakers/disconnects and battery temp sensors), the Magnum Battery Monitor, a PV Ground Fault device, and AC branch breakers (that can be used in lieu of an AC sub-panel to power the inverter’s AC loads). These additional breakers are installed on a supplied Din-rail mounting bracket that has space for up to six 13mm sized AC or DC breakers.

The E-Panel includes a DC Breaker used to disconnect the battery bank from the inverter as required by the National Electric Code (NEC). This breaker is also used as an overcurrent device to protect against extremely high currents that a battery is capable of producing if any short circuits occur. A variety of DC Breaker options are available from MidNite Solar.

Next to the DC Breaker is a 500 amp/50 mV shunt with a DC negative bus-bar attached. The shunt is provided so that a Battery Monitor, which is used to determine the battery bank’s state of charge, may be easily connected without any rewiring. The DC negative bus-bar provides a DC negative connection point for any DC loads or PV Panels in the installation.

Located on the right side of the E-Panel system is an AC input disconnect and an inverter bypass switch. The AC disconnect is used to remove the incoming AC power to the inverter input. The inverter bypass switch is provided to easily route the incoming AC power around the inverter and directly to the AC loads in the system - without rewiring or losing power to the AC loads in the system - in case the inverter needs to be removed.

3.0 InstallationBefore installing, read the entire installation section to determine how you are going to install your E-Panel. The more thorough you plan in the beginning, the better your overall system needs will be met.A basic system diagram for the MNE-240 Series E-Panel is shown in Figure 2, MNE-240 Series E-Panel System Wiring Diagram. This diagram should be reviewed to assist you in planning and designing your installation.

Info: Installations should be performed by qualifi ed personnel, such as a licensed or certifi ed electrician. It is the installer’s responsibility to determine which safety codes apply and to ensure that all applicable installation requirements are followed.Info: It is easier to install and wire any additional accessories (i.e. breakers for charge control, the inverter, etc.) while the E-Panel is still lying horizontal on a table. Do as much as possible before mounting the E-Panel on the wall.

3.1 Door Confi gurationThe standard E-Panel ships with breakers on the right side and with a right hand hinge. The door will open to the right over the breakers. If for some reason you need the breakers on the right, but the door to open to the left, then you can purchase the left hand door (part number MNEleftdoorSTM-240).

Info: The circuit-breakers can be moved from the right side and reassembled on the left side of the chassis. Even though this is possible, it is not advised. Moving the breakers is very time consuming and the bypass switch will need to be re-positioned and rewired. It is much more effi cient to so spend the time before the installation to pre-determine and order the correct side (left hinge or right hinge door).

3.2 Knockout PreparationInfo: See Figure 3 for the location and dimensions for the knock-outs on the MNE-240 Series E-Panel.

Think about all the different wiring required and remove the appropriate knockouts before mounting the E-Panel. Knockouts for breakers and outlets are best accomplished using a straight bladed screw driver and hammer. A hacksaw blade is another way to cut them out.

Charge Controller BracketIf installing a Charge Controller, secure the charge control bracket to the E-Panel with two #10 x 3/8” sheet metal screws supplied.Inverter Remote BracketIf installing the inverter remote control, secure the remote bracket to the upper left hand side of the E-Panel with two #10 x 3/8” sheet metal screws supplied. When installing the bracket on the right side, use two sheet metal screws and one machine screw. The remote bracket hides the space of the AC outlet cut out, but the outlet still can be used with the bracket installed.

3.4 Installing Optional HardwareAdditional BreakersAdditional AC circuit breakers can be installed per the manufacturer’s instructions on the open DIN Rail in the E-Panel. This DIN Rail has locations available for six additional 13mm wide AC and DC circuit breakers. These additional circuit breakers can be used for such things as: solar, wind or hydro charge controllers, DC ground fault protector, AC and/or DC distribution center and more.

Info: MidNite offers 150VDC breakers in 1, 6, 7, 8, 10, 12, 15, 20, 30, 50 and 63 amps. AC breakers are available in 10, 15 and 20 amp sizes that carry the UL489 and UL489A branch circuit rating. MidNite also offers 30, 50 and 60 amp sizes that carry the UL1077 listing for supplementary protection but are not branch circuit rated; these breakers are rated for continuous duty and are usually used as AC disconnects.

To install additional breakers, remove the side breaker cover with the circuit-breaker cut-outs; see fi gure 4. Each 13mm wide breaker requires removal of two cut-outs and the 17.5mm wide breakers require removal of three cut-outs.

Caution: Torque the breaker terminals to 20 in. lbs. using a 1/4” wide fl at-blade screwdriver (do not use a 3/16” wide or Phillips screwdriver, they can damage the screw terminals easily). It is highly recommended to recheck all terminations after an hour and also conduct a pull test. You may be surprised that what you thought was a tight connection actually pulls out with little effort. Copper is a relatively soft metal and will continue to move under inadequate clamping pressure; a 20 inch pound of torque takes a lot of strength!

When installing DC and AC breakers together on the same din rail. Some local inspectors will require physical separation between the AC and DC breakers. There are UL listed plastic 2” x 6” insulators supplied with this E-Panel to fulfi ll this separation requirements; see fi gure 5.

Info: UL and the NEC allow mixing AC and DC wiring in this installation because the wire insulation is rated for the highest voltage encountered in the enclosure. Both AC and DC circuits are considered part of the same Renewable Energy circuit for this installation.

Figure 5, Insulators between AC and DC breakers



3.5 Locating and Mounting the E-PanelReview Figure 6, MNE-240 Series E-Panel Mounted to determine the mounting space requirements for the E-Panel with the inverter/charger and any other optional equipment that may be mounted.

Info: Do as much of the additional wiring as possible before hanging the E-Panel on the wall.

Install the E-Panel in a location that meets the following requirements:

The E-Panel must be mounted vertically on a fl at surface (such as a wall).

Do not mount the E-Panel near any fl ammable or combustible fl uid or components (i.e. paper, cloth, plastic, etc.) that may be ignited by heat, sparks or fl ames - they must be at a minimum distance of 2 feet away from the E-Panel/inverter.

his E Panel system will weigh approximately 100 pounds. The mounting surface and hardware must be capable of supporting at least twice the weight of the E-Panel/inverter combination.

The area must be free from any risk of condensation, water or any other liquid that can enter or fall on the inverter.

Locate the E-Panel and inverter system as close to the batteries as possible. Long DC wires tend to loose effi ciency and reduce the overall performance of an inverter. However, the unit should not be mounted where it will be exposed to gases produced by the batteries. These gases are corrosive and will damage the inverter; also if these gases are not ventilated and if allowed to collect, they could ignite and cause an explosion.

Ensure the E-Panel is accessible after it is mounted. Select a wall that has suitable clearance to open the door with the inverter attached. It must also have adequate clearance to operate the breakers and outlets that protrude out the sides.

E-Panel Mounting Procedure

Info: Prior to mounting the E-Panel to the wall, ensure the bottom mounting bracket has been installed and the door has been removed.

1. Use a level and hold the top mounting bracket on the wall in a horizontal position and mark on the wall where you want the mounting screw holes.2. If required, drill holes using a #10 (0.193” diameter) drill bit. Drill appropriately sized holes for anchors when installing on non-wood surfaces.3. Secure the top mounting bracket to the wall using the three ¼ X 1½ hex-head lag bolts. If mounting to other than a wood wall or surface, use appropriate screws and anchors as required.4. Lift the E-Panel and place the keyhole slots (located in the upper back of the E-Panel) directly over the mounting screws on the mounting bracket and lower into place.5. Tighten the top mounting screws to secure the E-Panel to the mounting bracket. 6. Secure the bottom mounting bracket to the wall.

3.9 DC Cable WiringIt is important to use the correct DC cable and corresponding circuit breaker to achieve maximum effi ciency from the system and reduce fi re hazards associated with overheating. See the MS-AE Series Owner’s Manual to determine the minimum DC cable size needed based on your inverter model and the total cable distance.

Pre-DC Wiring ChecklistDC wires and cables should be tied together with wire ties or electrical tape approximately every 6 inches. This helps improve the surge capability and reduces the effects of inductance, which improves the inverter waveform and reduces the wear of the inverter’s fi lter capacitors.The DC cables/wires must be color coded with colored tape or heat shrink tubing: RED for positive (+); WHITE for negative (-); and GREEN for DC ground.It is important to route the cables so the doors close freely without undue force.The inverter uses 5/16” bolts and requires cables having ring terminal lugs with a 5/16 hole. Torque these bolts between 10 to 12 foot-pounds.To ensure the maximum performance from the inverter, all connections from the battery bank to the inverter should be minimized. Any additional connection may contribute to additional voltage drops and may loosen during use.The DC cables must be a fi ne strand super fl exible, such as Cobra cable (or equivalent) and be approved for residential wiring per the NEC (THW for example).

Caution: The inverter is NOT polarity protected; the battery’s negative and positive terminals MUST be correctly connected to the inverter’s negative and positive terminals before turning ON the DC battery breaker or damage will occur. The inverter’s warranty doesn’t cover repair to the inverter from this damage.Caution: The battery bank voltage MUST match the inverter’s required DC voltage (i.e. 48vdc battery for a 48vdc inverter) or the inverter may be damaged. Info: After making the battery connections, cover the outside of the connection with petroleum jelly or another form of battery terminal anticorrosive grease. Do not put anti-corrosion grease between the terminal and the battery cable.

Connecting the DC cablesRefer to fi gure 13 for connecting the cables in the following steps:

Info: Figure 13 shows the battery cables coming from below, but the E-Panel has knockouts that allows the cables to come from the sides or back.

Connecting the Inverter DC Cables1. Route the pre-wired positive (+) battery cable from the DC disconnect in the E-Panel through the grommet/door and connect to the positive battery terminal on the inverter.

2. Route the pre-wired negative (-) battery cable from the DC shunt in the E-Panel through the grommet/door and connect to the negative battery terminal on the inverter.

Connecting the Battery DC Cables1. Route a DC cable from the negative (-) battery terminal of the battery bank through the conduit/E-Panel knock-outs and connect to the open terminal on the DC shunt.2. Route a DC cable from the positive (+) battery terminal of the battery bank through conduit and connect to the bottom (source) side of the DC disconnect.

Connecting the Battery Temperature Sensor (BTS)1. Connect the BTS ring terminal end to the negative terminal on the battery bank. Route its cable from the battery bank through either the 3.5” or 1” hole in the E-Panel door and connect to the inverter’s RJ11 BTS PORT (yellow label).

3.10 AC WiringThe full AC pass-thru capacity of the MS-AE Series inverter/charger is 30 amps for both AC legs (AC HOT 1 and AC HOT 2). To obtain the full pass-thru capability of the inverter and protect the inverter’s pass-thru relay, use a maximum 30 amp double-pole breaker, which corresponds to a cable size of #8 AWG (THHN) in conduit. If you are using other wire sizes, please refer to your local electrical code for breaker requirements.Pre-AC Wring Checklist

AC input to the inverter requires a maximum 30 amp circuit-breaker to each of the inverter’s AC Hot inputs. If the dual-pole AC input disconnect in the E-Panel is rated for 30 amps, it will meet this requirement.AC Loads powered by the inverter will need to installed into an electrical sub-panel; or optional branch-rated breakers may be may be installed in the E-Panel and used to power these AC loads.Always use properly rated circuit-breakers. If using an electrical sub-panel, circuit breakers can be moved from the main electrical panel to the sub-panel only if the breakers are also listed to be installed in the sub-panel.AC wiring must be no less than 10 AWG (5.3 mm2) gauge copper wire and be approved for residential wiring per the NEC (THHN as an example).

Connecting the AC wiresConnecting E-Panel AC Input/Output Wires (refer to Figure 12 and 14 for the following steps):1. Route two wires [AC hot 1 (black/L1) and AC hot 2 (red/L2)] from a double-pole circuit breaker in the main panel and connect to the AC HOT IN 1 and AC HOT IN 2 bus-bars in the E-Panel respectively.2. Route a wire from the neutral bus-bar in the main panel and connect to the NEUTRAL bus-bar in the E-Panel.3. Route a wire from the ground bus-bar in the main panel and connect to the GROUND bus-bar in the E-panel.4. Route wires from the AC HOT OUT 1 (black/L1), AC HOT OUT 2 (red/Leg 2), NEUTRAL and GROUND bus-bars in the E-Panel and either connect to: A) the sub-panel, or B) to each individual circuit breaker if installed in the E-Panel.Connecting to the Inverter AC terminalsBefore connecting the wires to the inverter’s AC terminal block: 1. Ensure the wires are routed through the 3.5” grommet in the door; and 2. Establish the correct length of wire by opening and closing the door, then cut back the wires as required.

Info: Remove the AC access cover to expose the AC terminal block in the MS-AE Series Inverter as described in owner’s manual.

For the following steps, refer to fi gure 4-5 to locate the #8 AWG wires in the E-Panel:1. Connect the black wire labeled AC HOT OUT to the inverter’s AC HOT OUT 1 terminal.2. Connect the red wire labeled AC HOT OUT to the inverter’s AC HOT OUT 2 terminal.3. Connect the white wire from the NEUTRAL bus-bar in the E-Panel to either one of the inverter’s AC NEUTRAL terminals.4. Connect the black wire labeled AC HOT IN to the inverter’s AC HOT IN 1 terminal.5. Connect the red wire labeled AC HOT IN to the inverter’s AC HOT IN 2 terminal.

Info: A ground wire from the E-Panel to the inverter AC ground terminal is not required, because the inverter is suffi ciently grounded through the E-Panel to the permanent ground system. A ground wire may be connected from the GROUND bus-bar in the E-Panel to the inverter’s AC GROUND for additional redundancy.

3.11 Final Installation Tidbits:Wiring the Inverter Remote Control

Refer to fi gure 13 for the following steps:

1. Connect one of the RJ11 connector ends of the remote communication cable to the back of the remote; refer to the ME-RC owner’s Manual for specifi c information.

2. Route the other RJ11 connector end through the E-Panel and E-Panel door and connect to the inverter’s RJ11 REMOTE PORT (blue label).

Additional Accessory Wiring

Before attaching the DC cover to the inverter end, if you have any of the following inverter accessories, then you will also need to route their connecting cables through the E-Panel (and pass through the small snap-in grommet in the door) to the RJ11 Ports on the inverter:

• Automatic Generator Start Controller (ME-AGS) for automatic generator starting an stopping.

• Battery Monitor (ME-BMK-NS) for determining your batteries State of Charge.

• Simple ON/OFF adapters (ME-RSA, ME-RSA-M) that allow the inverter to be remotely turned on/off.

See the appropriate accessory owner’s guide or further information about the installation and confi guration of these accessories.

Installing Inverter Shield/Covers

Refer to fi gure 1 to identify the following components:

Upper Shield - Attach the upper shield to the E-Panel door using three 10-32 x 3/8” machine screws and kepnuts.

DC Cover - Attach the DC cover using four 10-32 x 7/16” taptite screws and at least one #10 internal tooth star washers.



4.0 Start-up and TestingAfter the DC and AC wiring has been completed, a series of voltage checks should be performed to ensure the system wiring is correct. If any of the tests fail, recheck the AC wiring.Before beginning, ensure all circuit breakers pertaining to the E-Panel system are OFF, this includes:

all circuit breakers in the main panel from all AC sources (utility or generator, if any) feeding the E-Panel.all circuit breakers in the sub-panel (if used).all circuit breaker within the E-Panel, this includes the AC Input disconnect, the DC Disconnect Breaker, and any additional AC or DC breakers installed.

A. Testing the Inverter AC Output Wiring1. Slide the Inverter Bypass switch to the “INVERTER” position and turn the battery DC disconnect to the ON (up) position.2. Turn ON the inverter as outlined in the MS-AE Owner’s Manual (or ME-RC Owner’s Manual if using a remote control). The inverters should be providing 120/240 VAC to the E-Panel AC Output Bus-Bars (ensure the inverter is not in search mode).3. Inside the E-Panel enclosure, use an AC voltmeter and measure the inverter voltage (Refer to fi gure 16 for the following voltage checks):

a. between the AC HOT OUT 1 bus-bar and the NEUTRAL bus-bar, this voltage should be 120 Vac (± 3%).b. between the AC HOT OUT 2 bus-bar and the NEUTRAL bus-bar, this voltage should be 120 Vac (± 3%).c. between the AC HOT OUT 1 bus-bar and the AC HOT OUT 2 bus-bar, this voltage should be 240 Vac (± 3%).

B. Testing the E-Panel AC Input/Output Wiring1. If the Inverter AC output voltages are correct (tested above): a) turn the inverter OFF; b) slide the Inverter Bypass switch to the “BYPASS” position; c) switch ON the circuit breakers in the AC main panel switch (from the generator or utility) feeding the E-Panel; and switch the AC input disconnect to ON. These tests assume that the AC input source (Utility/Generator) is 120/240VAC and that the neutral and ground are bonded together by the incoming AC source.2. In the E-Panel, use an AC voltmeter and measure the generator or utility voltage (Refer to fi gure 16 for the following voltage checks):

a. between the AC HOT OUT 1 bus-bar and the NEUTRAL bus-bar, this voltage should be 120 Vac (± 3%).b. between the AC HOT OUT 2 bus-bar and the NEUTRAL bus-bar, this voltage should be 120 Vac (± 3%).c. between the AC HOT OUT 1 bus-bar and the AC HOT OUT 2 bus-bar, this voltage should be 240 Vac (± 3%).d. between the NEUTRAL bus-bar and the GROUND bus-bar, this voltage should be <0.5 Vac.

3. If all voltages/tests are correct, a) turn the inverter ON; b) slide the Inverter Bypass switch to the “INVERTER” position; c) switch ON the circuit breakers either in the E-Panel or in the AC sub-panel, depending on which is used for the inverter AC loads. Verify the inverter is charging the batteries and powering the inverter AC loads.4. Secure all covers/panels on the E-Panel, inverter, main panel and sub-panel (if used).The MNE-240 Series E-Panel system is now tested and ready for operation. If the inverter needs programming or is not operating properly, refer to the MS-AE Series Owner’s Manual for setup and troubleshooting information.

5.0 OperationWhen 120/240 VAC power (Utility or Generator) is provided to the inverter/charger through the E-Panel, the battery charger function and internal transfer switch are enabled. This allows the batteries to be kept fully charged and pass incoming AC power through the inverter to power to the AC loads that are connected to the inverter. If the incoming power fails or the generator stops feeding the E-Panel, the inverter function automatically is enabled to keep the inverter AC loads from be interrupted. See the MS-AE Owner’s Manual for more information on it’s setup and operation.

Main Battery ShutoffThe Battery Disconnect Breaker (see fi gure 1) is used to provide overcurrent protection for the battery and inverter DC cables. This disconnect can also be used to disconnect the battery during battery maintenance.

AC Input DisconnectThe AC Input disconnect is a dual-pole 30 amp circuit breaker. It allows full pass-thru capability of the MS-AE inverter when switched ON. This breaker can be switched OFF to remove power to the E-Panel from the incoming AC source (utility or generator). With this switch OFF and the inverter turned off, the inverter, the connected loads, or any other installed equipment beyond the E-Panel can be serviced.

Inverter Bypass SwitchThe Inverter Bypass Switch allows the incoming AC power (utility or generator) to be connected to the inverter AC loads either through the “inverter” or connected directly by “bypassing” the inverter. After AC power is provided to the E-Panel, the bypass switch is ready to operate, either in “INVERTER” mode or “BYPASS” mode. This simple switch uses a pair of double-pole 50 amp circuit-breakers behind a sliding switch plate, which allows only one of the breaker pair to be turned on at a time. This switch is wired between the AC source (utility or generator) and the electrical sub-panel (or optional output breakers if installed in the E-Panel). This switch can easily be moved to the “BYPASS” mode allowing the AC loads to continue to be powered if the inverter or battery bank needs to be serviced/disconnected - without any re-wiring.

INVERTER Mode: Normally the Inverter Bypass Switch would be left in the “INVERTER” mode. In the “INVERTER” mode, power from the utility (or generator) is routed to the ‘Bypass Switch’ and passes through the inverter’s internal transfer relay. After leaving the inverter, the power continues back to the bypass switch onto the sub-panel. In this mode, the AC power from the utility (or generator) passes through the inverter to the sub-panel loads; and if the AC power fails, the inverter automatically comes on to continue powering the sub-panel loads.

BYPASS Mode: In the Bypass mode, the power from the utility (or generator) routes through the Inverter Bypass Switch directly to the sub-panel. This mode allows the AC power to “bypass” the inverter and continue powering the sub-panel loads if the inverter or batteries need to be serviced or removed. While in this mode, the sub-panel loads will not continue to be powered if utility power fails or the generator is turned off.
